Although the development of China's bearing industry has achieved certain results, the current problems can not be ignored, the most prominent is the low-end products, high-end products also rely mainly on imports. The development of high-end bearings in China is seriously out of line with the development of China's machinery and equipment. What is gratifying is that some companies that have accumulated and are committed to innovation have made breakthroughs in developing high-bearing products. For example, Luoyang Zhongyue Precision Bearing Co., Ltd. specializes in R&D and production of P4 and P2 high-end precision bearings. At present, the company's machine tool bearings, spindle bearings, high-speed bearings and other market competitive advantages, especially the machine tool bearings, product quality and imported products can be equivalent.
Based on the backward development of high-end bearings in China, the "Twelfth Five-Year" development plan that has been introduced clearly states that the state will play a guiding role in industrial policies to support the development of the bearing industry. Under the guidance of the state, the access threshold for the bearing industry will increase, the high-end production capacity of low-end products will be controlled, and the research and development of high-end bearings will enter the high-speed stage.
Coal Hot Water Boiler Features
1. new type steam-water separation device, high steam quality
2.Separate the smoke by inertia, reduce original emission concentration of smoke, environmental protection and energy saving;
3. The unique backwater injection technology of the hot water boiler, prevents the tube from bursting and the water circulation is more reliable;
4. The boiler is package type, it will be assembled before delivery, reduced transportation and installation time and cost by more than 30%.
5. In the feeder there is push-pull type flashboard ash remover. The flashboard is heat resisting cast iron and has surface sealing structure, Prevent secondary combustion deformation and exhaust leakage.
